If you are saying that you executed the above command already, you are toast.
(I am presuming the above has a typo, and was actually /dev/mmcblk0 ).
That command will write zeros to the entire device, including areas outside of the file system partitions.
So unless you kept a copy of those areas that contain device and user specific data -
you have done an "erase all" the hard way.
